Examples of org.springframework.richclient.application.PageComponent

org.springframework.richclient.application.PageComponent
A page component is displayed within an area on the page associated with an application window. There can be multiple components per page; a single page component can only be displayed once on a single page. Components instances encapsulate the creation of and access to the visual presentation of the underlying control. A component's descriptor -- which is effectively a singleton -- can be asked to instantiate new instances of a single page component for display within an application with multiple windows. In other words, a single page component instance is never shared between windows. @author Keith Donald
